 Question Solomon: xy + x =28 x + y +4

I assume you are to solve this system of equations and the second should be $x+y=4.$ If this is correct then would solve the second equation for $y,$ substitute into the first equation and simplify. This will give you a quadratic you can solve for $x.$ I got complex solutions.
